You're just being very vague, so it's hard to give you good feedback. Nobody wants to bother giving you a laundry list of US/European schools, but if you give some more details (academics, research interests), someone may be able to give you better advice.

how r the opportunities in US and Europe?

Student visas are getting somewhat tricky in the US, but assuming you can sort it out it's doable. There's tons of great work, but you're unlikely to find funding on the masters level.
